Precipitation

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Moncenisio, the chance of a wet day over the course of February is essentially constant, remaining around 19% throughout.

For reference, the year's highest daily chance of a wet day is 36% on May 27, and its lowest chance is 17% on March 6.

Over the course of February in Moncenisio, the chance of a day with only rain remains an essentially constant 0% throughout, the chance of a day with mixed snow and rain remains an essentially constant 2% throughout, and the chance of a day with only snow decreases from 19% to 15%.

The average rainfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands. The thin dotted line is the corresponding average liquid-equivalent snowfall.

Snowfall

We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. As with rainfall, we consider the liquid-equivalent snowfall accumulated over a sliding 31-day period centered around each day.

The average sliding 31-day liquid-equivalent snowfall during February in Moncenisio is essentially constant, remaining about 1.2 inches throughout, and rarely exceeding 2.8 inches or falling below 0.2 inches.

Daylight saving time is observed in Moncenisio during 2018, but it neither starts nor ends during February, so the entire month is in standard time.

For reference, on June 21, the longest day of the year, the Sun rises at 5:44 AM and sets 15 hours, 39 minutes later, at 9:23 PM, while on December 21, the shortest day of the year, it rises at 8:07 AM and sets 8 hours, 44 minutes later, at 4:52 PM.

The solar day over the course of February. From bottom to top, the black lines are the previous solar midnight, sunrise, solar noon, sunset, and the next solar midnight. The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray.

Humidity

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The chance that a given day will be muggy in Moncenisio is essentially constant during February, remaining around 0% throughout.

The percentage of time spent at various humidity comfort levels, categorized by dew point.

Wind

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed in Moncenisio is essentially constant during February, remaining within 0.1 miles per hour of 5.0 miles per hour throughout.

For reference, on February 2, the windiest day of the year, the daily average wind speed is 5.1 miles per hour, while on August 10, the calmest day of the year, the daily average wind speed is 3.6 miles per hour.

The highest daily average wind speed during February is 5.1 miles per hour on February 2.

The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions, excluding hours in which the mean wind speed is less than 1.0 mph. The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).

Growing Season

Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).

The growing season in Moncenisio typically lasts for 2.7 months (82 days), from around June 18 to around September 8, rarely starting before May 30 or after July 8, and rarely ending before August 10 or after September 30.

The month of February in Moncenisio is reliably fully outside of the growing season.

Time Spent in Various Temperature Bands and the Growing Season in February

The percentage of time spent in various temperature bands. The black line is the percentage chance that a given day is within the growing season.

Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.

The average accumulated growing degree days in Moncenisio are essentially constant during February, remaining around 0°F throughout.

Data Sources

This report illustrates the typical weather in Moncenisio year round, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Moncenisio.

The estimated value at Moncenisio is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Moncenisio and a given station.

Other Data

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands.

We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
